CHARLES HUNT, OF WASHINGTON, DISTRICT OF COLUMBIA.

nnrnonrne GEAR.

Application filed May 17,

To all whom it may concern:

Be it known that I, CHARLES HUNT, a citizen of the United States, residing at lVashington, District of Columbia, have invented certain new and useful Improvements in Detaohing Gears, of which the following is a specification.

This invention relates to an improved detaching gear, especially adapted for use on life boats or other similar conditions where the load is connected in a plurality of places and must be released simultaneously at all points. I

The objects being to provide a detaching device wherein the supporting member is locked against accidental movement and re lease of the load by the weight of the load.

A further object being to positively operate the supporting member in both directions to further insure against accidental movement of the parts.

A further object being to provide the above and means for simultaneously releasing the load from a single place on the load in a simple, durable and inexpensive manner.

The above and other objects in view will appear in the description and be finally pointed out in the appended claims.

Similar numerals indicate corresponding parts in all the figures of the drawings in which:

Figure 1 is a longitudinal section of a life boat showing my improved releasing mechanism.

Figure 2 is a plan view of the parts shown in Figure 1.

Figure 3 is a detail side view, partly in section, of the detaching gear.

Figure 1 is a front view of the parts shown in Figure 4.

Figure 5 is a vertical section on line 5-5 of Figure 3.

Figure 6 is a View of the mounting member when used on metal steam boats.

Reference now being had to the drawings by numerals, 1 indicates the conventional form of life boat having mounted on its stem and stern posts detaching gear 2-2 of identical construction.

The detaching gears 22 are operated by releasing means extending preferably along the side of the boat from its ends to a point that is conveniently located where the operating means is mounted to operate the 1923. Serial No. 639,598.

detaching gears at the ends of the boat simultaneously by a single movement.

One of the detaching members is shown in detail in Figure 3 and consists of a casting or forging 3 havingthe vertical mounting portion 4 provided with perforations 5 through which securing means such as cap screws may pass to firmly securethe device to the stem or stern post of the boat.

From the rear or securing plate 3, a horizontal portion 6 extends from which ears 7 and 8 extend in an upward direction from either side of the member 6. From the outer edges of plate 6 bracket shaped braces 9 extend and form an integral part of the body of the detaching member.

Pivotally mounted on a pin 10 between the upwardly extending ears 8 is a boat line ring 11 having the enlarged portion 12 adapted to fill the space between the ears.

Pivotally mounted between the upwardly extending ears 7 is a rocking or holding arm 13, mounted near its center on pin 14 and provided with the extension 15 over which the ring 15 of the boat lowering tackle is adapted to engage.

The rocker arm 13 is also provided with a bifurcated extension 16 in which is pivotally mounted on pin 17 the upper end of a toggle or looking lever 18.

The locking lever 18 is provided with an inwardly projecting lug 19 so located as to rest, when the parts are in their set or holding position, directly above a shoulder 20 at the outer end of plate 6.

The bracket members 9-9 beneath the plate 6 extend out beyond said plate as shown at 21-21. Between the outer ends of the extensions 21-21 is an operating or tripping lever 22 pivoted on pin 23. Said lever 22 is pivoted intermediate its ends, the upper end being pivotally mounted to the lower end of locking arm 18, by pin 24: and the lower end being connected with the tripping and setting or retaining cables.

Rotatably mountedon pin 25, between the members 99, is an idler 26 over which the tripping cable is drawn. The detaching gears as described are mounted at the ends of the boat and are adapted to receive over the holding bars 15 the rings of the lowering tackle in a well known manner.

Located preferably near the center of the boat is the means for tripping the detaching gears and consists of a drum 27 mountsecured to the side of drum pass the tripping retaining cables 28 and 29 ed on a bracket 28*, the boat. Over said and setting or respectively.

As shown in Figure 1, the tripping cable from the stern of the boat passes around beneath the drum While the corresponding cable from the bow of the boat passes over the top of the drum and they are secured at their outerends, after passing around the idler 26, to the operating levers 22. The setting or retaining cables pass in opposite directions around thedrum to their as sociated tripping cables, and are secured directly to the operating'levers, thus providing fora single movement of the drum by the lever 40 in one direction to release both ends of the boats simultaneously, by drawing on the tripping cables, while at the same time slackening ofi on the setting or retaining cables to permit movement of the operating lever.

The cables preferably run over pulleys 41' and through supporting eyes 42 along the side of the boat and pass around pulleys 43 and then about pulley 44 andiinally in a direct pull to the detaching gear.

The operation is obvious and consists in supporting the boat on the holding bars 15 at the ends of the boat during the lowering of same, and when it is desired to release the boat, lever 40 may be swung over, cables 28-28 will operate lever 22 to trip the locking lever 18 and rock the holding arm 13 from which the tackle may readily slip and release the boat. Should the weight betoo great for the pins 2-for 23 and they should shear oil, shoulder 19 will drop to lug 20- and the holding bar will still maintain its position and the boat will not be dropped.

Having thus described my What I claim and desire to secure Patent is:

1. A boat releasing device, comprising a body portion, a holding bar ljournaled in the body and adapted to hold a member of the launching tackle, a locking lever, provided with a safety lug, an operating lever, and means for positively operating the operating lever to release or engage the tackle.
